Spark plug indexing washers INDEXING WASHERS

Jacobs Electronics recommends that spakplugs be indexed for maximum engine performance.   Indexing entails setting the orientation of each plug to ensure that the side electrode does not shroud the spark from incoming fuel mixture and cause incomplete combustion.    The job is made easy by Jacobs' ultra-high heat conductivity all brass sparkplug indexing washers.    Available for 12mm flat seat and 14mm flat or tapered seat plugs.   Includes 30 re-useable washers of assorted sizes and complete instructions.

Uphill Power Module UPHILL POWER MODULE

Jacobs Electronics has just released a new, unique and exclusive accessory for its industry-leading Pro Street ignition systems.    Called the Uphill Power Module or UPM for short, it connects to the Pro Street Energy Pak and modifies the energy pack's digitally controlled spark output upon sensing a vehicle's tilt or angle.    The increased spark output results in significantly better throttle response and eliminates plug fouling caused by extreme angles.    Ensures the hottest spark and best throttle response when off-road or 4 wheel drive applications need it most.
